Ambrosian & gregorian hymns for Quasimodo Sunday

Andrea del Verrocchio. Christ and Doubting Thomas. 1467–1483. Florence.
The hymns available for the traditional mass wed text, theology, and music exquisitely. I live in an english speaking community. English is an accumulative language. Ecclesiastical latin accumulated greek vocabulary, and hebraic theology. A song can refer to the sacrifice of the mass, the communion of believers, and the salvation of God's people now, and from Moses―or anytime from Adam to the last day.

Saint Stephen has had a latin schola for a year, it has finished an annual cycle, but some songs are being done for the first time, since the ordinary had to be learned first, and some members have joined during the year. One of the members studied for a doctorate in classical languages at the University of Pennsylvania, and can give spontaneous translation of the text. This with a little discussion amongst the members, in asides and questions becomes a mini symposium (without the drinking). Ablatives, gerunds and the importance of the fourth declension are mentioned in passing.

To-day has many names. I must mention, to-day fulfills the octave of Easter, and is also, then fittingly, Divine Mercy Sunday. Perhaps, most anciently, to-day is Dominica in albis depositis, the sunday of laying away the white (garment of baptism) is one which is reflected in an ambrosian hymn, which is not served well by the usual Neale translation.

Another song for today is, O fillii et filiæ. It deals greatly with T(h)omas’ doubt. Quando Thomas vidit Christum, pedes, manus, latus suum, dixit: Tu es Deus meus, alleluia. The uncertain Thomas shrinks at the staid Christ as he inspects his wounds.
